Any small block engine will fit into the NT as long that you can get it with a standard/threaded crank, the SG crank will not work in the NT. If you look at a .12 engine hen look at a .21+ engine you will notice the .21 engine's case is larger and the engine mounting ears/holes are spaced differently. So the engines with a "small block" like what's on .12's will mount in ok but you cannot mount a .21 "big block" engine in w/o making your own mounts and other crazy stuff. I don't think there is any .12 or .15's that are big blocks, the .18's I think vary from brand to brand if they are big or small blocks but maybe they are all small blocks, I am not sure on that. Just before you buy a 18 engine check out the case and engine mounting ears/holes to see if they measure up the same as any .12 engine.

.12, .15, and a .18 will fit the xxx-nt. Only the threaded standard crank shafts will work. For racing I use the fantom fr12 and that is a great engine for performance and reliability. I have also heard great things from the fantom fr18 to but I haven't tried any .18 engine just heard things.

My cousin had alot of problems with the cvr motors he was going through a piston and sleeve every week becasue it would lose compression and it would never stay tuned and never run under 250 at idle or under throttle no matter where you set it. he got a new O.S. TR.12 and hasent had any problems with it and it screemes.

so it comes with a stock rear exhaust manifold..do they have a kit with a side exhst manifold? what brand of engine do u recommend? side and rear exhaust..what allen type of allen drivers do we need? sizes?

The original AD1 came with a side exhaust header, but the AD2 will come with the rear exhaust header and leave the side-port up to you.

I like Trinity's Sirio engines for both side and rear exhaust, although I've been running a Rossi rear-port for a few weeks and loving that engine as well.

Losi, AE, MIP, Trinity, Integy, Hudy, etc. all make allen drivers. You'll want to pick up a .050, 1/16, 5/64, 3/32. and 1/4 (I think I got that right). Go pick up last month's issue of Xtreme R/C for an article by yours truly on what to stock your toolbox with!

whoa!! xtreme rc mag writer? cool!!
i got one more question...is a standard crank only allowed on this truck? tnx for the info! actually local hooby shop here in the philippines said that the AD2 will be arriving here next week or two.. but my group here in our town will be purchasing the AD2's last week of JAN
